DEVICE FOR FEEDlNG PAPER TO CUTTlNG-MACHlNES.

Specification forming part of Letters Patent No. 37,791, dated February24, 1863.

To all whom it may concern.-

I Be it known that 1, JOHN F. SCHUYLER, of Philadelphia, Pennsylvania,have invented a device for feeding paper or fabric composed partly ofpaper to cutting apparatus; and 1 do hereby declare the following to bea full, clear, and exact description of the same, reference being had tothe accompanying drawings, and to the letters of reference markedthereon.

My invention consists of a device, fully described hereinafter, forfeeding sheets of paper to apparatus for cutting forms from the saidsheets, the device being especially useful for facilitating the cuttingof collars and other articles of wearing-apparel from sheets of a fabriccomposed partly of paper and partly of muslin.

In order to enable others to make and use my invention, I will nowproceed to describe its construction and operation.

011 refercnce'to the accompanying drawings which form a part of thisspecification, Figure 1 is a vertical section of my device for feedingpaper or fabric composed partly of paper to cutting-machines; Fig. 2, aplan view; and Fig. 3, a part ot'l ig. 1, drawn to an enlarged scale.

A is a table or platform forming a part of or situated adjacent to thebed of the cutting apparatus, the latter consisting of a knife made ofthe shape to which it is desired to cut the paper or fabric, and theknife being secured to a block arranged to slide in a frame B.

The cutting apparatus, which may be varied as regards construction andmethod of operating, forms no part of my present improvements; ithastherefore been deemed unnecessa ry to illustrate and describe it.

In the present instance the device is arranged to feed to the cuttingapparatus sheets of a fabric composed of paper and muslin combined, sothat pieces of the size and form of a shirt-collar may be out from thefabric. In a recess formed in the table A is fitted a rack, B, the teethof which are inclined on one Two plates, D and E, are hinged looselytogether bya pin, a, which also serves to connect the pawl F'loosely tothe ends of both plates. A lever, G, is hinged to a short bar, whichpasses through both plates, and the head h of which bears against theunder plate, E, a cam of such a shape being formed on the portion as ofthe lever Gr that on elevating the latter to the vertical positionshownin Fig. 1 the outer end of the plate D will be brought into contactwith the plate E. On depressing the lever, however, a spring 11 willelevate the upper plate to the position shown in Fig. 3.

In using the above-described device the attendant draws the two platesalong the table as far back from the cutting apparatus as desired; hethen places a number of sheets of the fabric one upon the other, and oneedge of this layer of sheets he places between the plates D and E,asseen in Fig. 2. He then raises the lever Gr, therebyfirmly clampingthe layer of sheets between the two plates. The attendant then pushesthe clamp, with its sheets toward the cutting apparatus. When the sheetshave arrived at a proper position for the knives to make the first cut,the long arm m of the pawl F will be in contact with the vertical sideof one ofthe teeth of the rack B.

After one set of collars has thus been out from the layer of sheets, theattendant places his finger on the short arm n of the pawl, therebyelevating the long arm at above the teeth he then pushes the clampandpaper forward until the long arm of the pawl (the short arm beingraised from the pressure of the finger) catches against the verticalside of another tooth of the rack, when the layers of paper are again ina proper position for being acted on by the descending knife, and thisoperation is continued until the whole layer of sheets has been cut upinto pieces of the desired form. It will be observed that the distanceof the teeth of the rack from each other, regulates the distance of onecut on the layer of sheets from the next cut, and the distance of theteeth from each other is such that the cutting of the layers of sheetsis accomplished with the least possible waste of material. The rack isso fitted to the table as to be readily removed, so that racks withteeth to suit collars of different sizes may be fitted to the table.

It will be seen without further description that the above-describeddevice not only facilitates the connection of feeding the fabric to thecutting apparatus, but is uncrring in its action, and ZLUL'OlllDllShQSthe desired end with the least possible waste of material.

A device similar to that described above may be used for facilitatingthe cutting of envelope-blanks or other forms from sheets of paper.

1 claim as my invention and desire to secure by Letters Patent- Theclamp composed of plates D and E, the c LHI-IGVOI' G, or its equivalentand the pawl I, the whole being constructed substantially as set forth,and operating in conjunctionwith a rack, B, as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOHN F. SCHUYLER.
